Question

Hi,

I tried to add a Custom domain to my Azure App Service. Since then, I am getting '502 Bad Gateway' error.

Can you please tell me how to fix this error?

Regards,

Umar

Hello Umer Rashid,

Thanks for your question.

Try the following: Ensure the "Override with new host name" in backend settings is set to "Yes" and select "Pick hostname from backend target". Also, check the custom domain dns settings are correct and SSL certs are valid.

See: https://learn.microsoft.com/en-us/azure/app-service/app-service-web-tutorial-custom-domain?tabs=root%2Cazurecli
